IONic BondingEQ: How do simple and complex ionic compounds relate to anions and cations?

Ionic Compounds Occur between METALS and

NONMETALS

Happens when electrons are transferred from one atom to another.

Example: NaCl (Sodium Chloride) Non-Example: H2O

Ionic Compounds When atoms gain or lose electrons, atoms

are no longer NEUTRAL.

They become IONS with CHARGES.

The compounds that form in this way are called IONIC COMPOUNDS.

IONIC COMPOUNDS are very stable.

CATIONS As previously stated, ionic compounds

form between metal atoms and nonmetal atoms.

Metals on the left side of the periodic table give up electrons and become CATIONS.

CATIONS are positively charged Ions. These occur when there are more protons than electrons in an atom.

ANIONS The nonmetal atoms on the right side of

the periodic table tend to accept electrons and become ANIONS.

ANIONS are negatively charged atoms. This occurs when there are more electrons than protons in an atom.

Using the Periodic Table How can we use the periodic table to predict

IONIC COMPOUNDS?

What is an example of a simple ionic compound?

We know that in order to form ionic compounds we need a metal and a nonmetal. We use the periodic table to identify potential metal/nonmetal combinations through our knowledge of their location on the chart.

NaCl – Sodium 1 + Chlorine 7 = 8 Valence electrons

BeO – Beryllium 2 + Oxygen 6 = 8 Valence electrons

Using the Periodic Table What is an example of a complex ionic

compound?Na2O – 2 Sodium 1 (2) + Oxygen 6 = 8 Valence electrons

MgAl2- Magnesium 2 + 2 Aluminum 3 (6) = 8 Valence Electrons

Applying Charges Give an example of a simple ionic

compound. Label the anion and the cation.

Give an example of a complex ionic compound. Label the anion and the cation.
